Filed: 1965-03-23
Abstract: 1,120,322. Valves. DOWTY MINING EQUIPMENT Ltd. 20 June, 1966 [23 Maroh, 1965], No. 12329/65. Heading F2V. [Also in Division F1 A pressure relief and by-pass valve responsive to pump delivery pressure and to the pressure of lubricant supplied to the pump bearings, comprises a valve member 11 exposed to the pump delivery pressure at port 7, and a piston 6 exposed to the lubricant pressure at port 5. The valve is used in a high pressure pump for oilin-water emulsions, an auxiliary pump supplying the emulsion to the pump bearing surfaces at low pressure. The piston 6 acts on valve member 11 through spring 15 which determines the maximum pump delivery pressure when the lubricant pressure is sufficient to hold piston 6 in its lowermost position, as shown. When lubricant pressure is too low, as when starting the pump, piston 6 is moved to its uppermost position by springs 25, and the pump delivery is by-passed by valve 11 to port 8. Stem 22 vents the lower side of piston 6, and prevents rotation of piston 6 when plug 16 is rotated to adjust spring 15.

Title: Improvements in the treatment of ores, metallurgical products, residues and the like for the recovery of precious metals
IPC: C22B5/02
Filed: 1928-05-01
Abstract: 316,063. Powell, A. R., Deering, E. C., and Johnson, Matthey, & Co., Ltd. May 1, 1928. Matte processes for platinum group metals.- Metals of the platinum group are extracted from ores, especially copper-nickel ores, and from concentrates, residues, sweeps, &c., by smelting to a matte, forming in or adding to the matte a proportion of free metal of the iron group, or an alloy thereof, which acts as a collector for the platinum metals, and adding a disintegrating agent, such as sodium sulphate or hydroxide, carbonate or sulphide of an alkali or alkaline earth, whereby, on cooling, the free metal crystallizes out in coarse crystals and matte is produced which disintegrates on exposure to the atmosphere; the matte is then crushed and the free metal crystals are separated mechanically, as by a magnetic separator or a shaking table, and treated for the recovery of the platinum metals. The matte may be cooled in ladles and poured off after a crust, rich in platinum metals, has been formed around the ladle, or it may be cooled in conical moulds and the lower part of the matte broken off, or it may be cooled in a furnace at a temperature at which the free metal separates out as a sponge and the still fluid matte tapped off; in each case, both parts of the matte are then subjected to disintegration and mechanical treatment and the free metal in the richer parts may be worked up by fusion with sodium sulphate and silica into a nickel matte amenable to direct wet treatment to recover the platinum metals and nickel, while the free metal in the poorer parts may be used again as a collector in fresh matte.

Abstract: 634,583. Making parts of aircraft. GOODYEAR AIRCRAFT CORPORATION. May 16, 1947, No. 13211. Convention date, Nov. 26, 1946. [Classes 83 (ii) and 83 (iv)] Angular bending; stretching; stamping.- A step in a process for making an airfoil and more particularly a leading edge for a helicopter blade comprises applying a longitudinal tension to a blank so as to tension it strongly, but below its elastic limit and then gripping the tensioned blank at closelyspaced areas and applying additional stress to permanently bend the blank therebetween. A blank 1 of sheet stainless steel, formed with holes 2 and slits 3 is bent longitudinally to U-shape in cross-section and placed in a tensioning and bending device. This comprises a pair of heavy members pivoted at 7, connected on one side of the pivot by a pressure cylinder 6 and at the other side formed as jaws with portions 8 adapted to be tightly clamped on to the blank, suitable filler blocks being placed within the blank. From each jaw extends an elongated channel-member 9 having at its outer end a plate 11 secured by bolts 12 to a clamp 13 or 14 adapted to grip the ends of the blank. The blank is placed in the device in the position shown in dotted lines in Fig. 3, the clamps 13 and 14 are tightened and the bolts 12 turned so as to put the blank under a tension which never exceeds and is preferably ten to twenty per cent below the elastic limit. The clamps 8 are then tightened on to the work and the jaws move apart so as to stretch a short length of the blank to beyond the yield point and give it a permanent bend as indicated in full lines in the Fig. 3. By turning the jaws over and arranging the pivot at the end as shown in Fig. 4, the blank is given another bend in the reverse direction near its other end. The bent blank is then trimmed as indicated by the full lines 16 in Fig. 5, so that the curved bottom part is shorter than the top, formed by straight upper edges 15 which are then bent at right angles along the line 15a to form a flange by which the blank is clamped by a member 18 within a channelled member 17. By supporting the member 17 by a number of clamping frames 21, a former 20 may be slowly forced down into the blank so as to draw it to the required final form, after which the ends are cut square and the flange removed.
